MACHINE FOR MAKING HINGES.

Specification of Letters Patent No 10,943, dated May 16, 1854.

are placed, and then introduced, one by one,

by means of a feedingslid'e, before dies where the knuckles are turned, by means of punches, and the finished hinges then ejected from the machine.

To enable others skilled in the art, to make and use my invention I will proceed to describe its construction and operation, reference being had to the annexed drawings forming a part of this specification, in Which Figure 1, is a top view. Fig. 2, is a longitudinal vertical section drawn through the lines 1, 1, in Fig. 1. Fig. 3 is av similar view drawn through the lines 2, 2, in Fig. 1. Fig. 4c is a perspective View of a complete machine. Fig. 5, is a vertical cross section through lines 3, 3 in Fig. 1. Fig. 6, is a similar view through lines 4, 4:, in Fig. 1. Fig. 7 is a side-view of the feeding-ways. Fig. 8 shows the manner of attaching the end of the lever 19 to the feedingslide. Fig. 9 is a view of the preventor in the feedingways. Fig. 10 is a bottom-view of the preventor. Fig. 11, is a top-view of gage, S, showing the position of the prevento-r 0. Fig. 12 is a vertical section of the same through lines 5, 5 in Fig. 11. Fig. 13 is a top-view of the feeding-slide. Fig. 14 is a sectional View of the bandwvheel with frictional coupling; Fig. 15, skeleton hinge before being operated upon by the machine. Fig. 16, appearance of hinge after having received the first curve; Fig. 17, the knuckle completed.

The skeleton hinges Z having been placed within the feeding-ways U U, 7) and T, in a horizontal position one above the other, motion is communicated to the bandwheel, W, whichimparts movement, by means of the shaft B, to the cam Q. Consequently the lever Q is made to move upon its axis R with a vibrating motion; and the lever Q being connected with the feeding-slide in the manner shown at Fig. 6 and Fig. 8 a horizontal movement is imparted to the slide P. The lower hinge is now carried by the catcher '0, out of the feeding-Ways, before the die L. The sliding-punch J, operated by eccentric C now comes up and presses the hinge against the die L, and gives it the first curve, as shown in Fig. 16. At the next revolution of the shaft the feed ing-slide returns, and the catcher 4) takes another hinge, the previous hinge being retained by the preventor 1*, andcarried by spring-catcher w in front of the 'die L, where the hinge Z receives thefinishing turn, by means of the sliding-punch J in the manner as shown at Fig. 17. At the third revolution of shaft 13 this hinge is again prevented from returning with the feeding-slide P by means of the preventor r (Figs. 11 and 12) and the spring'catcher w carries it out of the machine.

Dies L L are adjustable by screws f f, and bolts 6 e draw them down to these set screws, while bolts (Z and cl fasten the dies against bed P. To prevent plate Z from rising while the plate Z is in front of the die L, gage O is used, which is adjustable by set-screw z and bolt j to the thickness of the plate Z. This gage O has also a motion lengthwise which is also used to insure the correct curving of plate Z. Whenpunch J advances, set-screw K comes in contact with bolt j and pushes slide M and gage O forward, spring it throws it back, and set-screw,

. g, determines the length of the motion. 15'

Punches J J are adjustable to the width of plate Z by set screws a and a which bear against an upright shoulder on slides G G in Figs. 1 and 2. The length of the motion of punches J and J can be adjusted by setscrews 0 and 0 in Figs. 1 and 2 which work in studs K and K and strike against a lip extending from slides G G. The slides G Gr are worked by the eccentric, C, having rodsE E sliding within hollow rods F F.

These hollow rods are hinged to the slides G G. To the lower parts of the slides G G are attached arms H H; and to the lower ends of these arms spiral springs I I are fastened. When the revolution of the cam has pushed forward the eccentric rods E E and with them the slides G G the springs suddenly withdraw the slides G G as fast as the eccentric permits, until the slides G G come in contact with set-screws c-and c.

Fig. 14 shows the arrangement of the adjustable friction coupling. The pulley or gear W is placed on the shaft B against the shoulder 13. The friction nut X is now screwed up against the pulley or gear so tight ,as to give friction enough to the pulley or gear to drive the machinery. The j am-screw X is now screwed up against the nut X and holds the nut X in its position. Now if by an accident or other cause the machinery becomes deranged, or any foreign substance should intervene to prevent the proper operation of the machinery, the work is entirely stopped by the pulley WV becoming a loose pulley. Thus it will be per ceived that by means of the adjustable friction coupling more or less power may be communicated to the machinery as may be desired.

The feeding-ways seen in Figs. 1, 4, and 7 consist of an uprightpiece T having slots on one side through which the set-screws, p

7 is furnished with an angular gage which the preventor 1 works. This angular gage 1s regulated by the set-screws p by pass. These set-screws p sustain an uprightpiece U which is adjustable to the width of the plates. 7), is another adjustable side of the feeding-ways having slots on accommodate the sizes of the hinge that is desired tobe retained by them.

The lower part of the upright piece Fig. U, in

means of which it can be adjusted to the thickness of the hinges; and set so that only one plate can pass through on tothe feedingslide at one time.

The frame A where the feeding-ways stand is furnished with a feather T having a corresponding groove 2' the bottom part of the upright piece T. The bottom part-of the upright piece has a slot through which a bolt, Y, passes by means of which the entire ways are fastened to the frame A. The bolt, Y, permits a longitudinal adjustment of the ways.

Having thus described my invention I claim 1. I claim the slides G G, regulated by set screws, substantially as described.

2. I claim the eccentric rods E, E, sliding within the hollow rods F ,F, and connected with the slides G G.

3. I claim the sliding punches J, J, with adjusting-screws, arranged as set forth.

4. I claim the slidinggage, O, with its longitudinal motion and set screws, for the purpose of securing the hinges while turning the knuckle, in the manner substantially as set forth. I

5. I claim the fast gage, S, with the preventor r.

6. I claim the slide P, with the catcher '1) and the spring-catchers 'w, 'w.

7 I claim the gage U, in combination with the preventor r, for the purpose of preventing the hinge from returning with the feeding-slide; the whole being arranged and combined in the manner set forth, or in any other manner substantially the same.
